Letters Patent No. 114,886, dated May 16, 1871.

lMPROVEMENT IN PAPER-RULING MACHINES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it mag concern Be it known that I, J AMES TREGURTHA, ofCharlestown, Middlesex county, Massachusetts, have invented, made, andapplied to use certain Improvements inthe Construction of Paper-RulingMachines; and that the following is a full, clear, and correctdescription of my improvements, reference being had to the accompanyingdrawing making part of this specification andvto the letters ofreference marked thereon, in which-'- Figure 1 is a side elevation'of myimproved paper- -rnling machine.

Figure 2 is a side elevation of the same.

Figure 3 is a transverse section of the. same, the front portion of themachine being removed. Figure 4 is a detached view of the clamp'Q.

In the drawing like parts of the .inventi'on are pointedout by the sameletters of reference.

The nature of the present invention consistsa. In the use or employmentof the-adjustable standards in combination with the adjusting-screws,for the purpose of adjusting the position of the penbeam, as more fullyhereinafter set forth.

b. In the use or employment of the extension or over pen-holders, asmore fully hereinafter set forth.

0.. In combining with the pen-regulator a rest or support, as more fullyhereinafter set forth.

d. In the means employed when notinuse.

e e. In the use or employment of a striper, as more fully hereinafterset forth.

, vf. In the use of a clamp, 9, as more fully hereinafter described.

To enable those skilled in the art to make and use my improvements, Iwill describe the same.

A shows a frame for supporting the operative parts of my improvedmachine, which frame may be made of wood or any suitable material;

B shows the endless belt or apron to receive and carry the paper to beruled beneath'the pens; this belt or apron is made in the usual manner,of any suitable material; V

C shows the pen-roll, secured in boxes held in the rear end of the frameA; and

Dis the back-cloth roll, placed behind the penroll O, and held inadjustable boxes secured in the frame A.

E is the driving-cloth roller, held in boxes secured in the forward-endof the frame A, and over these rolls 0, D, and E the endless belt orapron B is stretched suflicientl'y tight, so that, as motion is impartedto the driving-cloth roll, as hereinafter described, the belt or apron Bwill move'freely over the rolls 0, D, and

Upon one-end of the driving cloth roll is keyed a Y gear-wheel, F,gearing into the gear-wheel G, secured upon the frame A, over which andthe adj ustahle cordroll I, held-also in boxes in the rear end of theframe,

the cords K, employed to hold the paper upon the belt or apron duringits transit through the machine, pass.

This roller His supported upon a shaft, L, upon the end of which issecured a crank or handle, M, by which the machine is operated.

Attached to the under side of the frame A, about midway its length, arethe hangers N, intended to receive the guiding-rollers 0, held in thesupports P, secured upon the blocks Q, held. upon a cross-piece,

placed in the hangers N, which hangers are made adjustable.

About the center of the cross-piece Q is secured a standard, R, in whichis placed a nut, 'r, by which the screw 8, attached at one end to aplate connected to the blocks Q, is operated, so that by turning the nutr the guiding-rollers O are advanced or withdrawn angular-1y to the sameextent.

These guiding-rollers 0, when placed in position in the machine, bearupon the under side ofthe endless belt or apron B, and serve to retainthe same in position upon the rolls 0, D, and E, as any tendency of thecloth to move sidewise upon the rolls while in motion is corrected bythe. rollers O placed angularly, and directing the cloth in a straightline, the back-cloth'roll having been first properly adjusted.

Upon the upper side of the frame A are secured the standards '1,employed in connection with the adjusting-screws U to adjust theposition of the penheain to the paper to be ruled; and the followingdescription of one will answer for both, as they are similar.

The standard is composed of a base-plate, a sliding plate, and athreaded upright, and upon the upper side of the sliding plate issecured a nut, V, into which the screw U works, so that as the screw isturned the sliding plate will be moved backward or forward, while in thethreaded upright the hollow screw X is inserted, having upon its lowerend a retaining-nut, Y, so that after the screw has bccn'sot in theproper position by tightening the retainingnut Y upon the screw X thesame will be held in position. Y

Z shows the support for supporting the pen-beam I. This support consistsof a spindleor stem, 2, which, when in position, enters the hollow-screwX and is free to move therein.

Upon the top of the stem 2 is formed the curved support 3, to receive amovable bearing, 4, in which the spindle or stern-5 of the pen-beam isreceived and is free to move.

It will be observed that this hearing is so constructed that it isself-acting or self-adjusting, which results from the fact that thebearings rest in curved supports, and that the curved portions of thebearings and the curved portion of the supports have a common center.

The spindle or stem. has a screw-thread out upon it engaging with orworking intoa female thread upon the interior ofthe movable bearing 4,and'by turning this screw-thread, by means of the nut 6, in onedirection or in the opposite direction, the pen-beam can be adjustedlaterally relatively to the frame A.

The vertical adjustment of the pen-beam is accomplished by the hollowscrews Y, in which rest .the stems or supports Z, provided with thecurved supports receiving the movable hearings, in which rest thethreaded and plain spindles 5 of the pen-beam, while the longitudinalmovement of the pen-beam is" accomplished by means of the sliding platesof the standards and the screws U.

pen-clamps 7 are constructed in the ordinary manner.

' Upon the back of the upper side of the pen-beam are placed the meansor appliances by which the extension pens are held. These consist of aplate .Qof

metal, 10, running the full length of the pen-beam and'secured upon thesame, a portion of the pen-beam being cut away to allow the metal toproject, as also to afford room for the introduction of the clamps '11.

The clam p 11 is provided with four claws or books, 12, which claws orhooks pass under the edges of the strip of metal when the clamp isplaced over the strip of metal The clamp 11 is also provided with aset-screw, l3, and the clamp having been passed over the strip of metal,one end of the extension pen 14 is inserted beneath the clamp betweenthe claws, rests on the strip of metal, and is held in position bydepressing the set-screw, which bears upon the extension pen and holdsit in position lengthwise while the claws or books prevent its lateralmovement. are free to move upon the strips of metal 10, thus adjustingthe position of the extension pens.

When a"gang of pens or one or more pens are to be employed, the compoundclamp (sec fig. 3) is used in connection with the strip of metal.

This is composed of the clamps 11 constructed about half the size of theclamp 11, and furnished with two claws or books instead of four, and thestrip 15; the ends of the extension pens restbeneath the strip 15 andupon the strip of metal 10, while the strip 15 is held in position bydepressing the set-screws in the clamps. The clamps and clamping-stripcan be placed upon any portion of the strip of metal 10, or may be made'to extend its full length, so that the position of the extension penscan be regulated anywhere along the full length, as desired.

The means employed by me to adjust the bearing of the pens to the paperto be ruled now should be spoken of.

They consist of a curyed arm, 16, held between the standards 17, andprovided with a hooked or ringed end, 18, serving as a handle for theoperator, and resting upon the block 23.

This arm is also provided with a link, 19, one end of which is held in arecess in the curved arm, while its'opposite end is held in a slidingplate, 20, dovetailed and moving in the ways 21, upon a plate, 22,secured upon one side of the pen-beam.

The clamps 11 To the rear end of the sliding plate is'secured' a stem,24, having a screw-thread out upon it'and moving freely in a threadedjournal secured'in a journalbox', 25, as the nut 26 upon the rear end ofthe threaded-stem is turned, by which movement the plate is moved in theways, carrying with it one end of the lowers the pen-beam, and thuscontrols the bearing of the pens upon the paper.

In connection with arm 16 the block 23 should be spoken of. This blockis of metal, and is hinged at one end to a sliding plate, 27, securedupon the upper portion of the frame A, and connected by a strip ofmetal, 28, to the sliding plate of the standard T, so that it shall bemoved in the same direction with the the arm '16. It is hinged at oneend, that it may be turned up and support the arm 16 when the pen-beamis lifted away from the work.

I will now speak of the striker, or device employed to raise or lowerthe ruling-pens at the proper time.

At the back side or edge of the pen-beam is placed a dovetail block, 29,of metal, over which is passed the dovetailed clamping end of a curvedarm, 30, intended to receive and support the striker, which armissecured upon the block of metal 29 by the set-screw 31.

-At the forward end of the arm 30 the striker is secured, being held inthe double clamp 32, provided with set-screws 33, placed at right anglesto .each other so that the striker can be adjusted longitudinally andvertically.

which is inserted and held in the vertical clamp, while to its other endis attached the striking-wheel 35, provided upon its rim with a seriesof set-screw holes.

In connection with thewheel is employed a series and. held upon the samein any desired position. by

openings.

These cams are so positioned upon the wheel that they shall, by beingbrought into contact with the paper as the wheel revolves, elevate thepen-beam and thus govern the contact of the pens with the paper to beruled, and thus regulate the distance between the lines ruled upon thepaper.

36 shows a stop-lever secured upon the upright 34, which lever hasattached to its forward end one end of a spiral spring, 37, the oppositeend of which is held on a pin inserted in the upright 34.

Against the stop upon this lever a pin, 38, secured in one of the spokesof the wheel, impinges when the wheel has made a full revolution.

upright 34, and provided with a stop, 40, with which the stop-lever 36is brought into contact, and also provided .at its other end with a cam,41., the lever 39 resting upon a pin inserted in the upright when inproper position to stop the lever 36.

Over the hub of the wheel 35, and free to move upon the same, is passeda lever, 42, provided at its upper end with an inclined surface, 43,against which the cam 41 bears.

At the other or lower end of this lever is hung a toot, 44, providedwith a toe, 45, which toe projects beyond the cams 35, secured upon thewheel, and rests upon the belt or apron after the wheel has completed arevolution. 7

Attached to the foot is a slotted are, which limits the movement of thefoot and toe, the are moving over a pin secured in the lever 42.

The lever 42 is held in position upon the hub of the wheel by means of asupporting plate, 46, passed over the other hub of the wheel and pinnedto the lever 42.

link 19, which, by its position being changed, raises or sliding plateand thus afford a constant support for The striker consists of anupright, 34, one end of of cams, projecting beyond the rim of the wheel,

means of the set-screws screwed into the set-screw- 39 shows astop-lever attached to a portion of the- 47 shows a spiral spring, oneend of which is attached to a spoke of the wheel and the opposite end tothe lever 42,-while upon the same spoke is held a check, the forward endof which. bears against the lever andstops it as the spiral spring 47contracts, when the lever returns after having been operated upon by thepaper.

A second sheet of paper to he" ruled, having been conducted beneath thecords upon the endless belt or apron to the wheel, is brought intocontact with the toe, which it carries with it suificiently far for theother end of the lever to lift the stop-lever by the inelined surfacebearing against the cam upon the lever. V

At-this point the friction between the paper and the wheel sets thewheel in motion, and the stop having been removed, the stop-lever isdepressed and the wheel continues to operate until the pin is again ibrought into contact with the stop, the stop-lever meanwhile havingresumed the proper position to stop the wheel.

48 is acam held upon the wheel by means of a setserew, and slotted foradjustment.

This cam is placed near the toe, is roundedon the side nearest the"advancing sheet, and is used forthe purpose of. lifting the pens 0d ofthe cloth or apron after the ruled sheet has passed through, and untilthe succeeding sheet is presented to be ruled.

The'side nearest the sheet is rounded to prevent it catching the edge ofthe sheet, and to pass it (the sheet) beneath the cam.

The operation-0f the machine in all respects notherein described issimilar to the ordinary ruling-machine, the sheet of paper to beruledbeing conducted to the ruling pens upon the belt or apron, andleaving the machine after ruling upon the same.

The clamp 9 is formed-of brass or any suitable metal, and is so shapedas-to receive the tongue of the pen-clamp.

The clamp is provided on the lower inside with a sliding plate, 49,which can be elevated or depressed as desired, by means of thethumb-screw 50, the-slid ing plate 49 bearing upon "the tongue of thepenclamp and serving to hold the same in position, in connection withthe upper portion of the clamp.

Having thus set forth my invention,

What I claim as new, and desire to secure by Letters Patent, is- A 1.The combination of the standards T, hollow adjusting-screws X,.supportsZ, and spindles 2, supporting the pen-beam, constructed and operatingsubstantially as and for the purposes set forth.

2. The combination of clamp 11 provided with setscrew 12, and the-stripof metal 10 secured upon the pen-beam, as and for the purposesspecified.

3. In combination with the curved arm 16, the block 23, hinged at oneend and connected to the standard T, substantially as and for thepurposes described.

. 4. The wheel 35, provided with the permanent stop 38, in combinationwith levers 36, 39, 40, and 42,

springs37 and 47,and toe 45, when the same shallbe constructed andoperate substantially as and for the purposes set fort-in I 5. The clamp9, provided with the .sliding plate 49 and set-screw 50, whenconstructed and operating substantially as described, for the purposesset forth.
